Abstract: PURPOSE:To improve the cooling effect of a supporting base member and prevent broken pieces  of a cylindrical spring member from mixing into combustion gas by a structure wherein the  cylindrical spring member, which has an upstream swollen-out part comprising a plurality of  longitudinal reeds and a center swollen-out part, is fixed by inserting itself onto the front combustion chamber supporting base member, the upstream end of which is expanded outward. CONSTITUTION:A bellmouth-curved plate part 32 is provided at the upstream part of a cylindrical supporting base member 21' continuously connected to a front combustion chamber 7. A cylindrical spring member 37, which is made of heat resisting spring steel and at the downstream end of which a bellmouth-tapered tube part 43 is formed, is fixed by inserting itself  onto a supporting base member 21'. The band-like swollen-out part 38 comprising a large number of longitudinal reeds 38' is formed at the upstream end of the spring member 37 and a  swollen-out part 39, the swollen-out amount of which is smaller than that of the swollen-out  part 38, is also formed at the center of the spring member 37. Owing to the structure as  described above, the spacings between a combustion chamber wall 30 and the upstream end of  the supporting base member 21' and between the wall 30 and the downstream end of the spring  member 37 become narrow, resulting in permitting the broken pieces of the reeds 38 to fall  down in the route as indicated with the arrow (b), not being allowed to pass through the  tapered tube part 43 as indicated with the arrow (a) and preventing the broken pieces of the  reeds 38 from mixing into combustion gas. In addition, owing to the space 36 formed by the  swollen-out part 39, the cooling effect of the base member 21' is improved.

Abstract: PROBLEM TO BE SOLVED: To improve a semiconductor device in transistor characteristic, by a method wherein the element isolation film of the semiconductor device is lessened in crystal defect and interface level so as to restrain a leakage current from occurring in it, and a rapid thermal annealing is carried out so as not to affect an impurity profile. SOLUTION: A well is provided to a semiconductor substrate (S101), an element isolation insulating film is formed by thermally oxidizing the surface of the semiconductor substrate (S102), a guard ring is formed under the element isolation insulating film by implanting impurities (S103), and then the semiconductor substrate is subjected to an RTA(Rapid Thermal Annealing) where the substrate is rapidly thermally treated at a higher temperature than that at which the above thermal oxidation process is carried out (S104). Thereafter, a MOS transistor and a capacitor are formed by injecting impurities into the semiconductor substrate (S105, S106), then a hydrogen sintering process is carried out as an interface level reduction treatment (S107).  Crystal defects are repaired by RTA without affecting an impurity profile, and a reduction is made in interface level through an interface level reduction treatment, whereby a leakage current occurs less in an element isolation insulating film.
